Description

  The present invention relates to a woven fabric having both active irradiation and reflecting properties, and more particularly to a luminescent woven fabric composed of a light reflecting yarn and a light guide fiber yarn.

  Night lights, decorations or alarm systems are usually divided into two types. One of them is a passive reflection type device which does not require power consumption and achieves an alarm action by reflecting an external light source. In general, the passive reflection type device is often seen in the form of a plastic reflection rod or a reflection plate. However, since the material is hard and the light source cannot be reflected when there is no light source in the surrounding environment, the light emitting effect is lost.

  The other is an active irradiation type device, which mainly uses fluorescent light emission or lamp light emission. This device is high in brightness and is not limited to the environment, but the device is complex, large and expensive and is not suitable for warning labels or decorative patterns on clothes or ornaments.

  A conventionally known light guide fiber yarn is formed by applying a general plastic optical fiber to a carbon fluoride on a side wall and partially destroying it by a physical or chemical method to allow light to be emitted from a side surface. When a light source is supplied to the end of this light guide fiber yarn, the light beam marches along the light guide fiber yarn, and the reflective material on the side wall of the light guide fiber yarn is partially broken, so that the light beam gradually moves from this location. Leakage occurs, and the side surface of the light guide fiber yarn becomes light emitting. However, those composed entirely of light guide fiber yarns have insufficient flexibility and it has been difficult to increase the bending angle. Therefore, there is a need for an active irradiating fabric that is light and flexible and that can provide a uniform light-emitting effect and that is suitable for clothes, ornaments, bulletin boards or alarm devices.

  An object of the present invention is to provide a fabric having both active irradiation and reflection properties, which gives an effective illumination function to a place where a light source is scarce and is provided with an effective illumination function by adding a reflection property.

  Another object of the present invention is to provide a fabric that is light, flexible, portable and also has active irradiation and reflection properties, and can be suitably used for manufacturing articles such as clothes, ornaments, bulletin boards, and alarm devices.

  In order to solve the above-mentioned problems, the present invention provides a woven fabric having active irradiation and reflection properties formed by alternately weaving a plurality of warp yarns and a plurality of weft yarns. A light-reflective yarn is used as the warp, and a light guide fiber yarn that emits light to the outside is used as the weft. The warp yarns are woven to intersect with the other weft yarns in a form that does not intersect with any number of weft yarns lined up in succession. It is comprised so that the light ray and external light which are radiated | emitted from may be reflected.

  Furthermore, the present invention provides a woven fabric using a light guide fiber yarn and a light reflective yarn as weft yarns. Select the ratio between the light-reflective yarn and the light-guide fiber yarn, arrange the light-reflective yarn that is the warp yarn and the light-guide fiber yarn that is the weft yarn in a predetermined sequence, and the warp yarn that is the light-reflective yarn is similarly light-reflecting It is woven in a form that intersects the weft which is a sex thread.

  The light guide fiber yarn used in the fabric of the present invention is preferably an optical fiber that emits light from the side. Such an optical fiber can be connected to an illumination light source, such as an LED light emitting diode. It is more preferable that 1 to 7 light guide fiber yarns can be bundled and connected to the irradiation light source, and 3 to 5 light guide fiber yarns can be bundled and connected to the irradiation light source.

  The light-reflective yarn used in the fabric of the present invention is a light-reflective yarn having a circular cross section, square or triangle. In addition, the brightness range of the light-reflective yarn is desirably level 1 to level 10 defined by the gloss measurement method defined by the Taiwan Standard (CNS) standard CNS-7773, and is between levels 5 to 10. More preferred. Further, the ratio of the light guide fiber yarn and the light reflective yarn constituting the weft yarn (light guide fiber yarn: light reflective yarn) is preferably 20: 0 to 1: 7, and 20: 0 to 1: 5. Is more preferable. 20: 0 indicates that all the weft yarns are light guide fiber yarns.

  The present invention provides a woven fabric having both active irradiation and reflection properties, which can impart an active light emitting capability to the woven fabric by a light guide fiber yarn that is a weft connected to an active irradiation light source. In addition, using light-reflective yarns with reflective properties, the light-reflective yarns themselves and light-reflective yarns are alternately woven to reflect outside light and reflect light rays from the light guide fiber yarns. Thus, it is possible to provide uniform light while orienting the light rays in the same direction and increasing the light intensity. Furthermore, in the present invention, since the light reflective yarn runs by skipping multiple light guide fiber yarns that are weft yarns, the fabric is light and flexible, and the warp yarns that are light reflective yarns are also light reflective. By weaving across the weft, which is a yarn, weaving the fabric gives more flexibility.

  A fabric having both active irradiation and reflection properties according to a preferred embodiment of the present invention will be described. In the present invention, several examples and modifications are disclosed in which several kinds of light-reflective yarns having different luminances are used, and the ratio of the light-guide fiber yarns and the light-reflective yarns constituting the weft yarns is different. . Those skilled in the art in the technical field of the present invention can understand the present invention more clearly by describing a plurality of preferred embodiments according to the present invention, and make various changes within the scope of the right of the present invention. Is possible.

  The brightness of the light reflective yarn used in the examples is measured by the CNS-7773 gloss metric method described above, and the brightness is divided into 10 levels according to the reflective ability of the fiber. Among them, levels 1 to 3 are yarns that do not have reflective properties, or are referred to as fog surface yarns, and levels 3 to 10 are light reflective yarns that have reflective properties.

(Example 18)
This example is a modification of Example 14, and the warp yarn 302 shown in FIG. 3 is a light-reflecting yarn having a triangular section with a luminance level of 10, and a light guide fiber yarn 304 as a weft yarn and a luminance level. Ten light-reflective yarns 306 having a triangular cross section are used, and three light-reflective yarns 306 are arranged in succession between two light-guide fiber yarns 304. As shown in FIG. 3, each light reflecting yarn that is a warp does not intersect with a plurality of light reflecting yarns and light guide fiber yarns that are continuously arranged. The 18th fabric is obtained by weaving so as to intersect with the yarn 306.

A luminance test was performed on the first to eighteenth fabrics produced in Examples 1 to 18 above. In this test, the luminance of each fabric was measured by the luminance measurement method of Taiwan Standard (CNS) standard CNS-5064, and the relative luminance for each fabric was determined. Relative luminance is the ratio of the luminance of other fabrics when Example 6 having the highest luminance in Examples 1 to 18 is defined as 100%. The relative luminance thus obtained is shown in Table 1 together with the type of the light reflecting yarn used and the ratio of the light guide fiber yarn and the light reflecting yarn used as the weft yarn.

  From Table 1, the following features were found. The first feature is that the brightness of the fabric is improved with the light-reflecting yarn having a higher luminance level than the light-reflecting yarn with a lower luminance level. For example, when all the weft yarns are light guide fiber yarns, the luminance of the warp yarn fabric using the light reflective yarn of the luminance level 7 is higher than the luminance of the warp yarn fabric using the light reflective yarn of the luminance level 5, The brightness of the fabric is higher than that of the first fabric. As is clear from this result, the fabric of the present invention using the light-reflective yarn clearly shows an improvement in luminance as compared with the fabric material using the yarn that does not have the light-reflective property. .

  The second feature is the shape of the light reflective yarn. As shown in Table 1, when the ratio of the light guide fiber yarn and the light reflective yarn constituting the weft yarn is the same, the brightness of the fabric using the light reflective yarn having a triangular cross section is all circular light reflective yarn. It is higher than the brightness of the fabric used. This is because the light-reflective yarn having a triangular cross-section has a flat surface that easily reflects light rays, and when the use ratio of the light guide fiber yarn in the weft is the same, the triangular light-reflective yarn is more circular light-reflective. The brightness of the fabric is improved over the yarn. Similarly, the light-reflective yarn having a square cross-section can also improve the light reflecting ability of the fabric and achieve the effect of improving the brightness of the fabric.

  The third feature is the usage ratio of the weft light guide fiber yarn and the light reflective yarn. The greater the use ratio of the light guide fiber yarn, the higher the brightness of the fabric. On the other hand, when the ratio of the light-reflective yarn used for the weft is increased, the quality of the fabric becomes light and flexible, and the plane is alternately knitted with the light-reflective yarn (for example, the plane 308 in FIG. 3) and Both the light-reflective yarns themselves exhibit the effects of uniformizing active light and reflecting external light. The ratio range between the light guide fiber yarn and the light reflective yarn of the weft may be 20: 0 to about 1: 7, more preferably 20: 0 to about 1: 5.

  As described above, the present invention provides a fabric made of a light guide fiber yarn, connects an irradiation light source to the end of the light guide fiber yarn, and the fabric of the present invention has an active light emitting property. Another feature of the present invention is the use of light reflective yarns in the fabric. Reflects external light on a plane formed by alternately knitting light-reflective yarns and light-reflective yarns, reflects light rays from the light guide fiber yarns, aligns the light rays in the same direction, and emits light. Achieve the purpose of strengthening and equalizing. Furthermore, in the present invention, the weft yarn is composed of a light guide fiber yarn and a light reflective yarn, and the warp yarn, which is a light reflective yarn, is intersected with the weft yarn, which is also a light reflective yarn, thereby making the fabric more flexible. Can give sex.

  According to the present invention, the ratio of the light guide fiber yarn used as the weft yarn and the type of the light reflective yarn can be adjusted according to the application. For example, when the light emitting fabric of the present invention is used as an alarm label, the highest luminance is obtained in a fabric woven by crossing with a warp yarn using a light-reflective yarn having a luminance or a triangle or a tetragonal shape, using all light guide fiber yarns for weft yarns. Is given to exert a warning effect. In addition, for example, when applying the fabric of the present invention to clothes or ornaments, the flexibility of the fabric can be improved by using a light-reflective yarn in combination with a light guide fiber yarn as a weft and used for clothing or ornaments. Both upper comfort and luminous decoration effect can be given.

  Specific numerical values and ratios in the above-described embodiments, for example, luminance 5 or “1: 7” or the words “upward” or “downward” indicating the direction are used for easily explaining the contents of the device. There is no limitation on the scope of the present invention. The foregoing description is merely a preferred embodiment of the present invention, and does not limit the scope of the claims of the present invention. Those skilled in the art will be within the scope of the technology disclosed by the present invention.
